Application l'ed April 24, 1915, Serial No. 23,578

To all whom t may concern Be it known that I, GEORGE H. Ross, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and lmproved lVringer, of which they following is a full, clear, and exact description.

This invention relates to machines for expressing water, juices or moisture of various kinds from cloths, clothing, fruit or other commodities, and has particular reference to a device providing for the thorough extraction of iva-terror moisture from commodities by the application of a torsional force exerted through the rotation of a crank or its equivalent.

More denitely stated, among the objects of the invention is to provide a machine of the character indicated comprising a bag or receptacle of substantially cylindrical form and of a nature adapted to hold the commodity to be treated, means beingprovided to hold one end of the receptacle from lrotation while the other end thereof is connected to a head caused to be rotated by means of a shaft to which power may be applied in any suitable manner, one of the ends or heads of the receptacle vbeing adapted to slide toward vor from the other n to compensate for the torsional effect.

A further object of the invention is to provide adjustable means for supporting the receptacle in position for operation as lover a tub, vat or other container.

The foregoing and many other objects of thc invention will hereinafter be more fully described and claimed and illustrated in the drawingsl forming a part of this specification in which like characters of reference" indicate corresponding parts in all the views, and in which- Figure 1 is a side elevation of a preferred embodiment of the invention applied to a tub, one portion of the rear end of the device being in longitudinal section; Fig. 2 isy a plan view; Fig. 3 is averticaltransverse section on the line 3-3 of Fig. 1'; Fig. 4L isa front end elevation; Fig. 5'is a4 transverse section on the line 5 5 of Fig.`=1;'Figs.l6, 7 and 8 are detail sectional views on the corresponding lines of Fig. 4L; and Fig. 9" is an inside elevation of the front head.

The several parts of this device may be made of any suitable materials, and the relative sizes and proportions, as well as the Specification of Letters Patent.

Patented J une 20, 1916. v'Renewed November 22, 1915. Serial No. 62,919. l

general design of the mechanism, may be varied to a considerable extent without departing from the spirit of the" invention hereinafter more fully described and claimed. I wish it to be understood also that while I may hereinafter refer to the function of the machine as that of wringing clothes over a tub, such descriptionbeing adopted for convenience, the machine is adaptedffor many other,V analogous yuses.

Referring more particularly to the drawings, I show at 10 a suitable receptacle or container adapted to sustain the machine in operation andwhich will be termed hereinafter for convenience a tub.y At 11 is indicated the main frame element constituting a strut or bridge for'the top ofthe tub and constituting the main *support for the active portions of theV device. At the front end of the strut is formed a vertical slot 12 adjacent which are upwardly projecting flanges 13, and at the extreme end of the strut are downwardly projecting lugs'l'et through which binding screws 15 act against the outer wall of Vthe front portion of the tub, while opposite the same are other lugs 111 coperating with the inner wall of the tub.r At the rear end of the strut is a vertical slot'16 bounded, as above de scribed, at the sides by vvertical Yparallel flanges 17, and below said flanges are arranged parallel shoulders 18 which, together with the slot, form a guideway extending longitudinally of the strut. The rear end of the strut is provided'with a hole V19 in alinement with the longitudinal center of the guideway. v

The numeral 20 indicates a front upright or standard pivoted at 21 yin the front slot 12 and having a foot 22 bearing against the inner wall of the tub. The standard 2O has v a cross pin 23 above the pivot 21 and adapted to bear against the upper edges of the flanges 13. The upper end of the standard constitutes a tubular bearing 24 for a power shaft 25, the axis of which is maintained the outer end of whichV is secured any suitable power device exemplifed hereinas a tending rearwardly throughl the hole 19 and having a winged nut 31 or its equivalent sesubstantially parallel to the strut 11 and to l hand crank 26. A somewhat similar standl iic cured thereto for drawing the slide and rear standard 27 rearwardly. This standard has a cross pin 32 bearing upon the upper edges of the flanges 17 and is provided at its upper end with a tubular bearing 33 into which projects a tongue 34 rigidly secured to one side of the standard, as shown best in Fig. 3. When the parts are in normal operation, the axes of the bearings 24 and 33 coincide or are in alinement with each other.

At 35 I show a front head secured in any suitable manner to the shaft 25 and of any suitable construction for the purpose of supporting one end of a. reticulated member or cage 36 of any suitable construction, depending upon the character of the service to be performed by the machine, but indicated herein as being composed of a circular series of twisted wire members 37 connected or interlaced with which are circumferential members 38 of any suitable tough flexible nature. The head 35 is made in two parts, the part 35a being arc-shaped and pivoted at 39 to the main head portion 35 so as to swing outwardly around the pivot away from the axis of the shaft and bearing 24 leaving an opening in the cage 36 at one side. rlhe ends of the wire or cables 37 are n formed with ball-shaped heads 40 journaled in correspondingly formed sockets 41 in the outer wall of the head 35 and held therein by means of a removable ring or plate 42 which, like the main head, is made in two parts for movement toward or from eachother. Each of the cables 37 is adapted to pass radially inwardly toward the center of the cage through a peripheral Vslot 43 terminating in a flaring enlargement'44 to allow free movement of such cable during the operation of the device. At the other end of the machine is a rear head 45 having a swinging section 46 pivoted at 47 for relative movement similar to that already described in connection with the head 35 and the opposite ends of the cables 37 'have ball-shaped heads secured in the head 45 in the manner already described and locked therein removably by means of the pla-tes 42. It will be seen, therefore, that it is feasible and sometimes desirable to remove the cage 36 so as to replace it with another cage of a different character, depend ing upon the service to be rendered. It is also to be observed that the cage already described may constitute a substantially permanent part of the machine, and in order to avoid the necessity for frequent interchange of such parts, the cage described may constitute merely a support or reinforcement for a bag or auxiliary cage (not shown) which may be carried therein and serving to hold the commodity to be acted upon.

The rear head is connected to a tubular shaft 48 supported in the bearing 33 and Yhaving oppositely arranged longitudinal slots 49 into and through which said tongue 34 projects from the standard 27. A cap 50 or its equivalent closes the outer or rear end of the shaft 48. Between the cap 50 and the tongue 34 is a coil spring 5l which serves to hold or tend to hold the head 45 pressed rearwardly against the bearing 33 but adapted to yield to permit the shaft 48 and head to slide forwardly to compensate for the twisting or torsional effect of the cage 3G when the front head is rotated. lt will be noted that the tongue 34 positively prevents rotation of the rear head and the rear end of the cage. V

rlhe arrangement of the heads 35 and 45 is such that the movable section of each opens outwardly from the main section in a direction to insure the automatic or practically automatic closing of the same when the sha ft 25 is turned toward the right or in a clockwise direction as indicated in Fig. 4. ln other words, as indicated by the diagonal dotted lines of Fig. 2, the rear movable section 46 opens downwardly toward the left of the operator while the movable section 35a of the front head opens downwardly toward his right hand, and whether or not the cage is substantially closed by the operator before the wringing operation begins, the first effect of the turning of the shaft 25 will cause the main portion of the head 35 to move relatively toward the section 35a causing such head to close, and such action through the cables connected-to the portion of the head 35 on the other side of the shaft 25 from the pivot 39 will cause the section 46 of the rear head to move toward the non-rotary portion of the rear head, andthe cage cannot open automatically or on account of the rotation of the shaft 25 whether locked closed or not. If desired, however, a hasp such as indicated at 52 connected to the main head member 35 may overlap the movable head member 35n as shown in Figs. 4, 7 and S, said hasp being provided with a hole or socket 52 into which a keeper 53 is adapted to snap.

As shown by the detail views in Figs. G and 7, the periphery of each head is arranged in the nature of a flange .inclined inwardly with respect to the main portion of the head so as to bring any radial element of the flange perpendicular to a line leading therefrom to a point in the axis of the cage intermediate the heads. By this construe tion the draft of the cables 37 upon the peripheries of the heads will be borne approximately in perpendicular lines thereto.

With the parts arranged and supported as herein. shown and described, the operation may be briefly summarized as follows: `With the cage free and open and with the spaced edges thereof arranged, as indicated by the dotted lines t in F ig. 2, substantially parallel to the axis of the machine, the bag of clothes or other commodity to be treated may be dropped within the cage and then the cage may be closed as already described and locked if desired. A rotation of the shaft 25 caused by the crank or otherwise in a clockwise direction will cause the front head to rotate and the cage to twist as indicated in Fig. 1, and thereby apply suflicient pressure to the commodity to express the water or juices therefrom and without danger of damaging the texture thereof in any manner. l/Vhen sufficiently wrung which ordinarily may be accomplished by a very few turns of the crank, the front head will be returned to its original position and the cage will be opened for the removal of the commodity.
